Be 1t known that we, WILLIAM P. HAM-1 MoND and Tiinononn A. HAMMOND', citizens of the United States of America, residing:

in Passaic.I in the county of Passaic and vState of New Jersey, and Rutherford, in the county of Bergen and State oi- New Jersey, respectively, have invented certain new and useful Improvements in Inflation Devices, of which the following is a specificaf tire, as for instance in the ease of excess pressure, may be readily carried out, and whereby a gauge may be'united in Suc manner that a visual indication of the pressure in the tire may be had during the iniiating and deiiating. y

Other features of improvement will be hereinafter referred to.

An embodiment of the invention is illustrated in the drawings. In said drawings,'

F igure 1 illustrates a vertical sectional view of the coupling;

Fig. 2 illustrates the Coupling in combination vviith a pressure gaugeand a tube connected with an inflating device, and joined'to the valve casing of a pneumatic tire.

' In said drawings, A designa-tes the coupling device per se. The coupling A has a part al provided with a passage a2. The part al is adapted to be connected with a pneumatic tire, or other container, andis preferably provided With'a couplin sleeve a3l adapted to engage the screwt eaded having a passage (LG therein.

end of a valve casing B. The part a? of the coupling is also preferably provided witha deiiaioi' n4 for depressingV the siem of the tire valve when the couplingis colinected to the valve casing.

The coupling A also comprises a part a5 The part a,6 is preferably provided with a suitable stop or valve ci? adapted to be operated to open and close the passage therein. The stop or valve is preferably in the form of an ordinary tire valve having a valve stein which may he depressed to unseat the valve, and thereby permit air to pass. The coupling `A also comprises'a part al@ havingr va pas sage an therein. The coupling A also comprises another part a having a passage a1e therein. A pressure gauge C, of any 'suitable construction, and a tube D leading to a pump or other means adapted to supply air to inliate the tire, are Connected, one to one, and the other to the other, of the parts am and a of the coupling One or both of the parts a and a may be provided with suitable valves or sto devices al. These valves are preferably in the forni of an Ordinar tire valve having a stem adapted to be repressed to unseat the valve and permit the passage of air. The pressure gauge C may be provided with a deiiator c1 to depress a valve stem, where the part of the coupling to which it is connected is provided with a valve. Where the part of the coupling to which the pipe D is connected is provided with a valve, the pipe D'may be provided with a part d1 adapted to depress a valve stein.

The pipe D and the gauge C may be attached in a permanent manner to the coupling, but are preferably detachably connected, as shown.

Operation-The coupling being attached to a valve casing, and an intlating tube and a' gauge attached to the coupling, as shown in Fig. 2, air may be admitted throu h the tube D to the tire. The pressure of t e air in the tire will be indicated by the gauge C. If the tire be inflat/ed to an excessive degree, or if for other reason it be desirable to deflate the tire, the valve in the part v a may be opened, as by depressing the valve stem to unseat the valve, and air will pass from the tire to the open.

The invention may find expression in other forms and embodiments.

What is claimed is l. The combination of an inlating meansl and a pressure gauge, and a coupling adapted to be connected to a neumatic container, said coupling having va ve-controlled means of communication between said gauge and the pneumatic container and between said inlating means andA the pneumatic container, said coupling also having valve-controlled means for venting said pneumatic container.

2. A coupling having an opening for and a means for attaching an inllating means, alpriessure gauge, and a pneumatic container thereto, and means for venting the pneumatic container, said opening for the pressure-gauge being valve-controlled.

3. A coupling having an opening for and a means for attaching an inlating means, a pressure gauge, and a pneumatic container thereto, and means for venting the pneumatic container, said openings for the pressure-gauge and inflating means being valvecontrolled.

4.. The combination of an inlating means, a pressure gauge, means for connecting said parts to a pneumatic tire valve or the like, and a manually-operable means operatively associated with the first mentioned means for relieving the pressure in such pneumatic tire.

5. The combination of an inflating means, a pressure gauge, means for vconnecting said parts toa pneumatic tire valve or the like, and a manually-operable means operatively associated with the first mentioned means for' relieving the pressure in such pneumatic tire, said relief means comprising a manu- 'ing such valve, a passage for connection with a gauge, a passage 'for connection with a pump or the like, and a rehef passage,

and a manually-operable valve contained in said relief passage.`

8. An inlating device for tires comprising means for connecting said device with the interior of a pneumatic tire, an inilation passage-Way adapted to be connected with a pump or reservoir for conducting com` pressed air to the tire through said means of connection, a pressure gauge, adapted to be placed in communication with the interior oiq `)aid tire through said means of connection, and a manually operable valve adapted to vent air from the interior of the tire through said means of connection when there is an excess of air introduced into the tire, whereby air may be vented through said device Jfrom the tire Without removing said device or the hose leading to saidpump from connection With the tire, said means of connection with the tire, comprising a deflater adapted to contact with the stem of a valvepin an ordinary valve casing, and open it to allow the pressure `Within the'tire to act upon said gauge and to flow througlr to vent air from the tire.
